Vendors cannot pay for a score.
What size publisher is Sonix built for?
Sonix is built for small and local publishers, mid-market publishers and enterprise publishers. That is the vendor's own stated target, and it is one of the inputs to our publisher-fit score — a platform that suits a national newsroom often carries more operational load than a small one can absorb.

Pay-as-you-go $10/hour; Core $25/month (5 hrs), Advanced $50/month (20 hrs), Pro $80/month (40 hrs); extra hours $10; custom Enterprise. 30 minutes free. Our cost-of-ownership score is 4.3/5, which weighs pricing transparency, entry cost, implementation cost, hidden-fee risk and ongoing cost. Ask the vendor for a written first-year figure that includes implementation before you commit.
